In mathematics, informally speaking, a sequence is an ordered list of objects (or events). Like a set, it contains members (also called elements, or terms). The number of ordered elements …

While the idea of a sequence of numbers, a1, a2, a3, . . . is straightforward, it is useful to think of a sequence as a function. We have up until now dealt with functions whose domains are the …

Sequences are in nite lists of numbers a1; a2; a3; : : : ; an; : : :. Sometimes it is useful to think of them as functions from the positive integers to the real numbers, in other words, a(1) = a1, …

Since partial sums are sequences, let us first review convergence of sequences. Definition 1. A sequence (aj )∞ is said to be f-close to a number b if there. aj − b| ≤ f. (however small). We …

real sequence is just a list of real numbers in order. If Υ is replaced with ≤, then we have a complex sequence. In this course, we will almost always deal with real sequences.

6.0 Introduction and revision to the notion of a sequence, and its related series. You will also have encountered the use of the å notation as a shorthand for writing out series wi a large number …

A sequence is a real-valued function f whose domain is the set positive integers. (N). The numbers f(1), f(2), · · · are called the terms of the sequence. f(1) ≡ s1, f(2) ≡ s2, · · · , f(n) ≡ sn, …
